(3,14) because when you plug in the x and y values you don’t end up with a true statement.
F(x)=2(3)+9
F(x)=6+9
F(x)=15
14 does not equal 15

Find the ratio of book price to number of pages for each ordered pair. Round your answer to the nearest hundredth. A 3-column ta
Harlamova29_29 [7]

The ratio of book price to number of pages for the ordered pairs a, b , and c are:

  • <em>A = 0.05</em>
  • <em>B = 0.05</em>
  • <em>C = 0.043</em>

The ratio of book price to number of pages can be evaluated for each ordered pairs as follows;

  • For a = 20.00/400 = 0.05

  • For b = 6.25/125 = 0.05

  • For c = 15.0/350 = 0.043

Therefore, ratio of book price to number of pages for the ordered pairs a, b , and c are:

a = 0.05

b = 0.05

c = 0.043
